and, therefore, it is commonly safer to describe these latter as distinct 

 species, rather than to run the risk of allocating them at once to 

 the wrong males. 



This is the fiist record of N. Hutliwaitii (Cambr.) in Dorset.

An adult male was found by F. 0. P. Cambridge at Hyde in 

 1888. This is its first record as a Dorset spider ; it had previously

Cephalothorax, falces, maxillae, labium, and sternum dark reddish- 

 brown, closely and finely striated with scratch-like marks. It is of 

 the usual oval form, but the caput is greatly elevated, the upper 

 extremity divided into two lobes, the anterior the largest, sur- 

 mounted with a patch of short hairs, and bearing the two lateral 

 pairs and fore central pair of eyes ; the hinder lobe springs by a 

 small neck from the occiput, and bends over forwards in an 

 enlarged oval form to the extremity of the anterior lobe, with 

 which it is nearly in contact, leaving a narrow elongate fissure or 

 space between the two ; near the fore extremity of the hinder lobe 

 are the hind-central pair of eyes, separated from each other by 

 about two diameters' interval. The eyes of each lateral pair are 

 contiguous, and seated on the sides near the extremity of the 

 anterior lobe ; and the fore-centrals, which are placed a little aboVfe 

 the line formed by the two lateral pairs, are near together, but 

 (apparently) not quite contiguous to each other, and are smallest of 

 the eight. 



The legs are tolerably long, slender, bright yellow, tinged with
